Biology Unit 11

Big Idea:

Human systems and homeostasis. Nervous and endocrine systems. Respiratory and circulatory systems. Immune system and disease. Digestive and excretory systems. Protection, support, and movement. Reproduction and development.

Student Expectations:

Priority TEKS

B.10A describe the interactions that occur among systems that perform the functions of regulation, nutrient absorption, reproduction, and defense from injury or illness in animals

B.10C analyze the levels of organization in biological systems and relate the levels to each other and to the whole system.

Focus TEKS

B.4B investigate and explain cellular processes, including homeostasis and transport of molecules

Ongoing TEKS

B.2E plan and implement descriptive, comparative, and experimental investigations, including asking questions, formulating testable hypotheses, and selecting equipment and technology

B.2F collect and organize qualitative and quantitative data and make measurements with accuracy and precision using tools such as data-collecting probes, standard laboratory glassware, microscopes, various prepared slides, stereoscopes, metric rulers, balances, gel electrophoresis apparatuses, micropipettes, hand lenses, Celsius thermometers, hot plates, lab notebooks or journals, timing devices, Petri dishes, lab incubators, dissection equipment, meter sticks, and models, diagrams, or samples of biological specimens or structures

B.2G analyze, evaluate, make inferences, and predict trends from data

B.2H communicate valid conclusions supported by the data through methods such as lab reports, labeled drawings, graphic organizers, journals, summaries, oral reports, and technology-based reports

B.3D evaluate the impact of scientific research on society and the environment

Student Learning Targets:

• I will list and describe the different systems in the human body.
• I will explain how each of these systems work and what their main functions are.
• I will describe how all the systems work alone, or together to maintain homestasis.

Essential Questions:

• How do the levels of organization relate to each other and to the whole human body system?
• A system to maintain homeostasis must have at least four parts that function together. What are these parts, and what do they do? Explain your answer.
• What are three differences between the ways in which the endocrine system and nervous system work?
• What are the roles of the three types of neurons?
• What are some similarities between somatic nervous system and autonomic nervous system?
• How do hormones work and why are they important?
• How do the respiratory and circulatory systems help maintain homeostasis in the body?
• How do the structures of arteries, veins, and capillaries relate to their function?
• What are the primary roles of red blood cells, white blood cells, and platelets?
• How does the immune system work alone, and with other body systems to help prevent disease?
• How do the digestive and excretory systems help maintain homeostasis in the body?
• What are the main functions of the skeletal and muscular systems?
